Both the sale and sophistication of drones for the "amateur" market has increased no end in the UK, particularly at Christmas time. They have become quite ubiquitous, cheap and easy to purchase with plenty of variety and outlets. Drones are getting smaller, they have longer range, increased height capabilities, they have cameras, telescopes, gps systems, which can get them back home if they get lost. They can also have many other kinds of remote sensors fitted, at little extra cost, heat seeking capabilities, etc. Recently, there have been reports here in the UK about concerns expressed by pilots of commercial and passenger aircraft who have been "buzzed" or had "near misses" by drones flown by amateurs near airports. The police say that they, of course, take these complaints very seriously and are taking measures to catch the culprits and prevent it from happening. One does wonder exactly what measures and how many people have been prosecuted.
There are laws of course, which are quite stringent about where one can fly these things, guidelines and codes of practice on safety and privacy, and permission to enter the airspace of private property grounds. And no one wants to stop anyone having a bit of fun with them, as long as they are operated safely aand quietly.
Putting the two strands together, it won't be long before some terrorist organisation sees drones as weapons of mass destruction, just as our government sees them as surgical instruments for killing terrorists children through collateral damage. The question really...is how soon...
